How about a chance to play editor-in-chief? Fill in the blanks:
__________ would have been a much better book if ______________________.
Many books leave me wanting a different ending for the characters. The one that comes to mind is The Amber Spyglass, I sobbed my heart out at the end. But would I change it and keep Will and Lyra together? I don't think I would. The book would lose a lot if you changed the end. I read a blog post the other day about love lost and completely agreed with it especially this line;
"In the end, maybe it’s the longing for the love that can never be that touches readers more than the acquisition of that love".
I wouldn't change any book I had read and enjoyed. I might wish it different, I might rage against the author but I wouldn't change it because it would change the story and it's the story that I love.
Having said that there are a few books that could have used a heavy dose of editing the last three Harry Potter books and Diana Gabaldon to name a few.
